Chapter 3 Installation and Availability

You can install Unbreakable Enterprise Kernel Release 3 on Oracle Linux 6 Update 4 or newer, running

either the Red Hat compatible kernel or a previous version of the Unbreakable Enterprise Kernel. If you

are still running an older version of Oracle Linux, first update your system to the latest available update

release.

The Unbreakable Enterprise Kernel Release 3 is supported on the x86-64 architecture but not on x86.

3.1 Installation Overview

If you have a subscription to Oracle Unbreakable Linux support, you can obtain the packages for

Unbreakable Enterprise Kernel Release 3 by registering your system with the Unbreakable Linux Network

(ULN) and subscribing it to additional channels. See Section 3.2, “Subscribing to ULN Channels”.

If your system is not registered with ULN, you can obtain most of the packages from Oracle Public Yum.

See Section 3.3, “Enabling Access to Public Yum Channels”.

If you have previously installed any OFED packages on your system, and you want to replace these

with the latest packages that are provided on the ol6_x86_64_ofed_UEK channel, you must manually

remove some of the existing packages. See Section 3.4, “Upgrading OFED Packages”.

Having subscribed your system to the appropriate channels on ULN or Public Yum, upgrade your system.

See Section 3.5, “Upgrading Your System”.

3.2 Subscribing to ULN Channels

The kernel image and user-space packages are available on the following ULN channels:

• ol6_x86_64_latest (latest user-space packages for Oracle Linux 6 other than DTrace, OFED, and

DRBD packages)

• ol6_x86_64_UEKR3_latest (kernel-uek*, dtrace-modules-*, libdtrace-*, and uname26)

• ol6_x86_64_Dtrace_userspace_latest (dtrace-utils*)

• ol6_x86_64_ofed_UEK (latest OFED tools packages)

• ol6_x86_64_mysql-ha-utils (drbd84-utils)

The following procedure assumes that you have already registered your system with ULN.

To subscribe your system to a channel on ULN:

1. Log in to http://linux.oracle.com with your ULN user name and password.

2. On the Systems tab, click the link named for the system in the list of registered machines.

3. On the System Details page, click Manage Subscriptions.

4. On the System Summary page, select each required channel from the list of available channels and

click the right arrow to move the channel to the list of subscribed channels.

Subscribe the system to the ol6_x86_64_latest and ol6_x86_64_UEKR3_latest channels. If

required, you can also add the channels for the DTrace, OFED, and DRBD packages. You do not need

to subscribe the system to the ol6_x86_64_UEK_latest channel.
